Whisper AI for your desktop

Whisper AI,
wrapped in a desktop app.

OpenAI's Whisper is the most accurate open-source speech-to-text model ever built. But using it requires the command line. Mumbl wraps Whisper in a native desktop app with a global hotkey, filler word cleanup, text formatting, and paste-anywhere convenience.

The problem with cloud transcription

"For years, I relied on transcription tools that were almost good, but they were all closed-source...leaving me wondering where my audio really went."

Whisper is incredible but requires Python, command line, and technical setup. Most people can't use it even though it's free.

"I'll reconsider when local or self-hosted AI is available." — It's available now, in an app.

Mumbl packages Whisper into a native app. Download, install, hit a hotkey, speak. No terminal, no Python, no setup. Just works.

Three steps. That's it.

1

Hold down Option + Space

Or customize your own hotkey

2

Talk naturally

Say what you're thinking, ramble, use filler words. Mumbl cleans it all up.

3

Release

AI formats it instantly in your chosen style and pastes it wherever your cursor is.

Your voice never leaves your device

Mumbl processes everything locally using Whisper AI. No cloud uploads. No servers. No data collection. Your words stay yours.

As a developer who cares about privacy, I vetted the pipeline. Everything runs on-device. No network calls, no telemetry. Exactly what I'd build if I had the time.

Frequently asked questions

Is this actually using Whisper?

Yes. Mumbl runs OpenAI's Whisper model locally on your device. The model is downloaded once during setup, then all processing happens on your machine. Same Whisper, packaged in a real app.

Do I need Python or the command line?

No. Mumbl handles everything. Download the app, install it, and you're ready. Hit a global hotkey from any app, speak, and formatted text appears. No terminal, no dependencies, no configuration.

What does Mumbl add on top of Whisper?

Global hotkey from any app, automatic filler word removal, text formatting and style options, paste-anywhere convenience, and a native menu bar/system tray app. It turns Whisper from a developer tool into something anyone can use.
